AUTOMOBILE Application filed May 14,

My invention relates to improvements in automobile oil records, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a device of novel construction in which a record of certain data pertaining to the operation of a vehicle may be displayed. More specifically, I propose to so arrange a record that the operator may be informed as to the time when the oil was last changed and when it is to be changed again. Moreover,

the record will also show the type of oil 1grhich is being used in a particular automoile.

A further object of my invention is to provide an oil record device which is adapted to be placed on the instrument board of a car and so constructed that data may be readily and conveniently entered thereupon.

A still further object of my invention is to provide a device of the type described which is simple in construction, durable and efiicient for the purpose intended.

While I have shown onl the preferred form of my invention, I Wis 1 it to be understood that various changes or modifications may be made within the scope of the appended claim without departing from the spirit of the invention.

My invention is illustrated in the accompanying drawing forming a part of this application in which Figure 1 is a fragmentary perspective view of an instrument board showing my device connected thereto;

Figure 2 is a front elevation of my device;

Figure 3 is a transverse section taken along the line 3-3 of Figure 2;

Figure 4: is a fragmentary sectional view showing the fastening clip which I employ;

Figure 5 is an elevation of the recording chart.

In carrying out my invention, I provide a rectangular frame which is secured to the instrument board 2 of the car by any suitable means. In my illustration, I have shown the securing means as comprising OIL RECORD.

screws 3 which are threaded through inwardly extending flanges 1.

A wall 5 of the frame 1 has windows 6, 7 and 8 which are formed therein. The purpose of these windows will be readily understood as the specification proceeds.

Immediately in the rear of the wall 5, I place a transparent member 9 which may be glued or otherwise secured thereto. This member is preferably made of celluloid and is large enough to cover the three openings.

One of the side walls 10 of the frame is provided with a slot 11 through which a non-transparent celluloid member 12 is extended. Figure 5 shows this member as having a metal strip 13 clamped along one of its edges. This strip facilitates the withdrawal of the member 12 from the frame when the operator desires to change the record.

A fastening clip 14 is pivoted to the strip 13 as at 15 and is permitted to engage with a pin 16, (see Figure 4) which extends from the frame 1. The clip secures the record sheet to the frame but permits it to be easily removed therefrom.

Referring now to Figure 2, it is to be noted that the inscriptions Change oil at, oil changed at and Type of oil appear on the frame above the openings 6, 7 and 8 respectively. The member 12 is provided with dotted lines 17, 18 and 19 which serve as guide lines for writing.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Assuming that the oil supply has just been renewed, the operator raises the clip 1 1 until it disengages with the pin 16. The metal strip 13 is then grasped with the fingers and the record sheet is withdrawn from the frame.

The speedometer reading is now recorded on the line 18 provided for that purpose. At the same time the calculated mileage at which the oil should again be changed is entered on the, line 17 The type of oil may also be written in on the line 19.

The recording sheet is now replaced in its position within the frame and the clip 14 sheet being arranged in position to be seen 10 lowered into engagement with the pin 16. through said windows and being removable My device is thus perpetual in its operation through said slot a pin secured to said as the numerals may be easily removed with frame and extending therefrom, an edge 5 a damp cloth. strip secured to said record sheet, and a clip I claim: pivoted to said strip and adapted to engage 15 In a device of the type described, a frame with said pin for securing said record in having a slot and windows formed therein, position. a record sheet disposed in said frame, said RALPH'E. MAXWELL.
